Hello, this ain't so newbie of a question, but I am.Anyway, I was working on a game three weeks ago and something bugged me.I had split the screen after 64 scanlines when sprite0 hit. At the split I enable scrolling, wait 64 more scanlines, and there I have the screen scrolling the opposite way by decrimenting xscroll. That lasts 64 more scanlines, then I turn off scoll for the rest of the screen. But the weird thing was that the wait amount for the first and the second scrolling area was not the same. And when I added the second nametable of background graphics, then the two wait times were the same.So I guess if the second table is empy, somehow the ppu takes less time to get down?I can post the source if this is confusing. I suspect it's well known, like for title screens that scroll on from both sides, maybe. Not using scanline irq counters.No excuse for not searching this one. I'm sorry.Tyler
